In the last couple of days I was very eagerly looking for a time tracking application to replace the old pen & paper version, which I used in the last 6 months. There where only few requirements for it: simple interface, intuitive and unobtrusive towards my desktop (but that wasn’t a strict requirement). Along with some common sense features for a time tracker:

task tracking (doh!) stop and start timer

continue and pause task

time reports day, week and month

overviews of most time consuming tasks, or other features that make you feel warm and fuzzy
